To all whom it may concern `Be it known that I, JOHN A. Vm', a cit1- zenof the United States, residin at Erie, in the county of Erie and State oPennsylvania, have invented certain new and use ful Improvements inTube-Wrapplng Machines: and I do hereby declare the following to be afull, clear, and exact description of the invention. such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

y invention relates to tube wrapping machines and has for its object theconstruction of mechanism by means of which tape fabric may be wrappedaround a. tube to be vulcanized, and after the tube has been vulcanized,the said tape can be unwound from said tube and wound upon a pole, readyto be wound upon another tube.

In the manufacture of rubber inner tubes for vehicle tires, theunvuleanized gum is First formed into tubes, which unvulcanized gumvfubes are placed upon poles, usually metal pipe; and then theunvulcanized tube is tightly wrapped with strips of muslin or tape, inspiral form, after which the pole with the wrapped unvulcanized tubethereon, is place'iilll in the vulcnnizer to be cured. When the polewith the cured rubber tube thereon is removed from the vulcanizer, thewrapping tape is removed therefrom, and according to present practice,is rewound upon a spool b hand work or otherwise, as the case may e.

With my improved wrapping machine herein described, the pole with thecured rubber tube thereon, after being removed from the vulcanizer isreplaced in my wrapping machine, together with a pole without a tubethereon, and the tape is unwound from the cured rubber tube onto theempty pole, in` the same s iral form in which it was wrapped aroun thecured rubber tube; so that when the cured tube has been unwrappedanother pole with an unvulcanized gum tube thereon, can be placed in theinachine and the wrapping tape wound upon said unvulcanized gum tube inthe same form as in the case of the first tube; thus eliminating thenecessity of winding the wrapping tape upon a spool prior to thewrapping of a tube, and the necessity of guiding the tape inthe roperspiral during the wrappin of the tuliii.

hese an other features of my invention will a pear hereinafter in the sification and c aims, and are illustrate in the accompanying drawings,in which:-

Figure 1, 1s a plan view of mechanism embodying my invention.v Fig. 2,is a front elevation of the same, with a portion thereof broken away.

In these drawings A, indicates the frame of the machine, and A',indicates the su porting legs thereof. U n one end of t e frame A, placeshaft arings B B and B' B', and on the o posite end'of the frame I placebearings C and C' C In the bearings B B, I mount a shaft D, upon whichis secured a chuck-head D', having a central squared opening in the flatface thereof; and upon the shaft D,

tween the bearings B B, I place a pulley E, provided with frictionclutch mechanisni E', and an operating cone E2. This cone E2, ispreferably operated by means of a foot treadle F, and shaft F', which issupported in bearings F2, in the le A', from which treadle a rod G,exten s upwardly to bell crank mechanism G', which engages the cone E2.In the bearings B' I mount another shaft H, which is provided withachuek H', havin a uare opening in the Hat face thereo similar to thechuck D'. Upon the shaft H, I also place a pulley J, rovided withfriction clutch mechanism J and operating cone J 2, which operating coneJ2, is controlled by means o a hand rod K, and lever and rock shaftmechanism i said rock shaft K', and bell crank mecha ism G', beingjournaled in the frame of machine below the shafts D and H. I alsoprovide a hand brake lever L, which is pivoted to the machine upon thepivot l, and is provided with a spring l', adapted to normally maintainsaid lever out of I.zontact with the periphery of the chuck In thebearings (l, I place a slidable shaft M, provided with a spring M',adapted to maintain said shaft in the osition thereof shown in thedrawings, and) upon one end of said shaft I plac a cone-head M2, adaptedto project into the o n end of a pipe; and in the bearings C', place alike shaft N, rovided with a spring N', to maintain' shaft in positionthereof showimnfhe A from the clutch ot' the arrow and P', are

Fig. 1, of the drawings, E, will run freely on the shaft D; the rotationof said pulley being in the direction thereon; and the pole P, havingthereon a rubber tube with its wrapping tape Q, as it comes from thevuleanizer, 1s put in place between the chuck D', and the cone M2, andthe free end of the tape, as inbroken line Q', in Fig. l, is

' unwound therefrom' and placed around an ated to force empty pole P',supported by the chuck H', and cone N2; then the hand rod K, is oper thecone J2, toward the pulley J, so as to operate the clutch mechanism 1n'said pulley to cause the shaft H, to revolve.

tion of the pulley shaft H, causes the empty wound upon un winding ,Y onthe pole P',

The direction of the revolution of the shaft ll, and pulley J, being inthe direction of the arrow thereon, is opposite to the rota- E. Thisrotation of the pole P', to rotate of the cured tube with ,the same deinwhich it was R. During this from the cured and the shaft l), to therotation of and wind the tape Q, off ll, and onto the pole P', gree ofspiral and overlap the cured tube of the tape Q, rubber tu )e R, thepole P, rotate backward, opposite the pulley E, thereon.

lVhen the tape Q, has been entirely unwound from the rubber tube R, thep is replaced by another pole P, on which has been placed anunvulcanized rubber gum tube, and then the tree end of the tape Q, iswound around the end of the unvulcanized rubber tube, the cone J2,having been previously withdrawn from the clutch mechanism J. Then thecene E2, is caused to set the clutch mechanism in the pulley E, whichcauses the ole P, and green gum tube R, to rotate in t e direction ofthe arrow on the pulley E, and wind the tape Q, thereunto, from the poleP'.

During the winding of the tape Q, upon the green gum tube R, suflicientpressure may be exerted by the operator, upon the brake L, to put theproper amount of tension upon the tape Q, as it is being wound upon therubber gum tube R.

Having thus shown and described the mechanism embodying my invention, soas to enable others to utilize the same, I do not desire to limit myselfto the exact ronstruction shown and described, but

What I claim as new and desire to secure by Letters Patent, is

1. In a machine of the class described, a pair of poles, means torotatably support the same in parallelism, said poles being adapted toreceive a tape spirally wound thereon, and means to independently rotatesaid poles in opposite directions, whereby the tape is alternately andspirally wound from one to the other without traverse.

In a machine of the class described. means to rotatably support a tapebearing pole, means to rotatably support a tube bearing pole parallelwith said tape bearing pole, said poles adapted to receive a tapespirally wound thereon, and means to indrpendently rotate said poles inopposite directions whereby the tape is alternately wound from one tothe other without traverse.

3. In a machine of the class described, a frame, a head-stock andtailstock thereon. a pair of livrl spindles in said head-stock. a

Jpair of dead spindles in said tail-stock, a spirally wound tape-bearingpole supported between a live and dead spindle, a brake mechanismassociated with said live spindle. a tube-bearing pole supported betweenthe other live and dead spindles, a pulley and associated clutchmechanism on each of said live spindles, whereby said poles may berotated to spirally wind said tape Jfrom one to the other withouttraverse.

In testimony whereof I affix my signature.
